SHOCK-LOADER.

Specification of Letters Patent.

Application filed March 15, 1910.

Patented 1) cc. 2, 1913.

Serial No. 549,568.

To all whom it may concern:

Be it known that I, Gnonon A. Innorr, a citizen of the United States,residing at Grow, in the county of Roger Mills and State of Oklahoma,have invented certain new and useful Irmprovements in Shock- Loaders, ofwhich the following is a specification.

The object of my invention is to produce a shock loader that will pickup the shocks of corn, wheat, rye, etc., as they stand in the field, andautomatically load them on a wagon.

A further object of my invention is to automatically pick up hay, flax,etc, and load the same on a wagon; and with these objects in view, myinvention consists of the parts and combination of parts as will behereinafter pointed out.

In the drawings, Figure 1 is a top plan view of a shock loader embodyingmy invention; Fig. 2 is a side elevation of the same, parts being brokenaway; Fig. 3 is a detail sectional view on the line 33, Fig. 2; Fig. 1is a front elevation of the loader; Fig. 5 is a top plan view of thelock for the teeth of the gathering wheels, and Fig. 6 is a dctailperspective view of one of the gathering teeth. Fig. 7 is a perspectiveView of one of the cams.

1 represents a frame to which the draft tongue 2 is secured in anysuitable manner.

3 is a depending side member secured to the frame 1 and extending to apoint comparatively close to the ground. This side member forms one sideof the guideway to be hereinafter referred to.

4 is a traction wheel journaled on a spindlc which is secured to theside frame 3.'

5 is an elevator frame mounted on the main frame at a suitable angle andextend ing outwardly to one side of the machine, as shown in Figs. 1 and4, said frame being provided with an endless carrier 6 of suitableconstruction; the carrier being mounted on suitable sprocket wheels 8and 9. The shaft of the sprocket wheels 9 extends through the frame 5 atone end and is provided with a bevel gear wheel 10.

11 is a power shaft mounted in bearings 12. the inner end of the shaftbeing provided with a bevel gear wheel 13 which meshes with the bevelgear 10, and a sprocket wheel 14;, on which the power chain 15 ismounted.

16 is a large sprocket wheel on which the chain 15 is mounted, and bywhich said chain is driven from the axle of the traction wheel 17 to behereinafter referred to.

18 is an endless carrier suitably mounted on the side frame at the rearof the machine and provided with teeth 19. The endless carrier isprovided with shafts at each end on which are mounted sprockets whichare cmineeted by suitable drive chains. The driving shaft 20 of thecarrier 18 is provided with a driving gear which meshes with the gearwheel 20 mounted on a shaft 90 carrying a pinion on which is mounted thedrive chain 21, which is driven from a sprocket wheel 22 mounted on theshaft 11.

23 are arms extending transversely of the tongue at a suitable distanceforward of the front of the n'iaehine. The outer ends of these arms arebent downward as at 24L to provide journals for the gathering wheels.These gathering wheels are substantially conical and are each providedwith a hub 25 from which depends a spindle box 26 on the lower end ofwhich is secured a bevel pinion 27.

28 are spokes, one end of which is secured in the hub 25, while theother end. is socured in a rim 28 which is suspended thereby. As shownin the drawing. there are two of these gathering wheels. The extremelower end of the arms terminates in spindles on which the tractionwheels 29 are ournaled. These wheels 29 are of less diameter than thegathering wheels and are mounted within the gathering wheels, as clearlyshown in Figs. 1, 2 and 1.

30 are bevel gear wheels secured to the wheels 29 and mesh with thepinions 27 to revolve the gathering wheels. The rim of the gatheringwheels is provided with a number of depending gathering teeth 31 whichare loosely mounted in said frame. These teeth are bent to form a rightangle portion 32 which has a bearing in the rim 28 and again bent atright angles to form the portion 33 which is substantially parallel withthe inner face of the rim 28 and extends in the direction thereof, asshown in Fig. 5. 3 is a plate secured to the depend ing arm 2 .1: andextending less than half the circumference of the rim 28. This plate341- bears on top of the portion 33 of the pins or teeth 31 and holdsthe pins rigid in order that they may perform their function ofgathering, but as soon as the teeth pass from under said plate theyfreely swing in the rim 28 on the portion 32 and thus offer no m terialpassing between it and the side 3 from passing through said wheel.

37 is a disk mounted on the spindle of the wheel 17, on the periphery ofwhich are anumber of pairs of lugs or cars 38 between which spokes 39are pivoted by means of the bolts 40.

41 is a ring secured to the outer face of the wheel 17 by means of thetubular spacing members 42, said members being provided with anelongated slot 43.

44 are flanged rings fitted over the spacing members and riveted theretoby means of the rivets 45. 46 are bolts securing the spacing members tothe wheel 17 and ring 41 as clearly shown in Fig. 3.

The spokes 39 are provided with sockets 47, in which a shank 48 isslidably mounted, said shank having on its upper end a ball 49 which ismounted in the tubular spacing member and adapted to move freelytherein; the shank 48 moving in the elongated slot 43. The ball 49 has arecess 50 with sides diverging, in which is pivoted one end of a speartooth 51, the other, or free end of the tooth, extending through anenlarged opening 52 in the wheel 17.

The disk 37 is provided with a flange 53 which terminates in a cam face54 at each end. The disk 45 is similar to the disk 37 and is providedwith a flange 56 terminating at each end in a cam face 57. These twodisks are alike and are mounted rigidly on the spindle 36 with theflanges 53 and 56 on opposite sides of the spindle so that the flange ofone disk is opposite the flat portion of the disk, thus forming acontinuous cam groove in which the spokes 39 move. The disk 37 with itsspokes is mounted on the spindle 36 between the disk 37 and 55 with thespokes projecting through the cam groove formed by the flanges 53 and56. There is a series of the tubular spacing members disposed at regularintervals around the wheel 17 near its periphery, and in each is mounteda spear tooth 51.

The operation of the machine is as follows: The machine is propelledalong a row of shocks with the wheels astride the row so that the shockis positioned between the depending side 3 and the wheel 17. As thecenter of the wheels is opposite the shock, the spear pins or teeth 51to the rear of the center of the wheel are gradually projected throughthe openings 52 and pierce the shock and the revolution of the wheel(the teeth traveling with it) elevates the shock and car ries it to apoint immediately above the endless belt 6 when the teeth are withdrawnfrom the shock, thereby permitting the shock to fall upon the belt whichin turn conveys itto a wagon which travels beside the loader. As thewheel 17 revolves, the disks 37 and 55 are carried with it, whichresults in moving the spokes 39 in and out by means of the cam grooveformed between the disks, which in return results in the ball 49 movingback and forth in the spacing member 42, the shank 48 sliding in thegroove 43 and reciprocating in the socket 47, which causes the spearteeth or pins to reciprocate to pierce lift and release the shock. Themechanism is so timed and the cam groove so formed that the teeth willnot be projected until the .shock is about the center of the machine andwill be withdrawn as the shock is positioned immediately above theelevator 6. The teeth are not projected simultaneously, but aregradually and successively projected. If the shocks are loosened by windor from any other cause, the gathering wheels 28, by means of the teeth31, push them and all stray bundles in line with the path of themachine, and as soon as the teeth pass from under the plate 34 they hangloose and drag, thereby obviating all danger of.dragging the loosebundles out of the path of the machine. The traction wheels 29 throughthe bevel gear 30 serve to operate the gathering wheels by reason of itsengagement with the bevel pinion 27 These gathering wheels also serve togather loose hay, etc., into the path of the machine, so that it will bein position for the pins 51 to gather it up and deposit it on theelevator 6. In the event that any material escapes the teeth 51, Iprovide the endless carrier 18 which is driven by means of the chain 21in a direction opposite to the travel of the machine which sweeps thematerial up for engagement with the teeth 51. The chain 21 is drivenfrom the shaft 11, which in turn is driven from the chain 15 whichreceives its power from the sprocket 16 on the wheel 17. The carrier 6is driven by means of the bevel gear wheels 10 and 13. I provide atrough or other suitable receptacle at the foot of the endless carrier 6to catch any grain that might drop from the shock as it is loaded on thecarrier.
